Golden Alga Bloom Reports

Please note: Evidence of a golden alga-related fish kill is often difficult to track. Large numbers of small fish may be killed. Predators such as birds and raccoons may eat larger dead fish before they are observed or counted. Also, dead fish quickly sink below the surface, which interferes with counts. Estimates of numbers killed are only as good as the evidence available on the scene. The public is asked to report dead or dying fish and wildlife as soon as possible to TPWD's 24-hour communications centers at 512-389-4848 (Austin) or 281-842-8100 (LaPorte).
